"Is that why you visit here?" I ask, "Because you think Dad's a sad…sad…."

"Sadist?"

"Yeah"

The Death Eater man cocks his head to one side and looks hard at me. "Where did you learn that word?"

"You said it to Mum. You said to Mum that she married a man with sad tentacles".

He laughs again. "Sadistic tendencies maybe? Accusing James Potter of having sad tentacles would be a rather puzzling insult".
